The Flatpak framework for distributing Linux desktop applications is now in prodaction release, after three years of beta status. The framework, originally called XDG-app, is intended to make Linux more attractive to desktop app developers. Applications built as a Flatpak can be installed on just about any Linux distribution.
The open source FlatPak can be used by different types of desktop applications and is intended to be as agnostic as possible when it comes the building of applications. There are no requirements for languages, build tools, or frameworks. Users can control app updates. Flatpack uses familiar technologies such as the Bubblewrap utility for setting up containers and Systemd for setting up Linux cgroups (control groups) for sandboxes.
